Doesn’t get much better: On the back of the Holy Bowl T-shirts worn by Cathedral Catholic students was this message — The Best Rivalry In San Diego.

Tough to argue. St. Augustine’s stands were packed more than an hour before kickoff. Cathedral’s side was filled 40 minutes before the start. The game was a sellout by Tuesday.

Saints’ purple-clad student body let out a raucous yell 20 minutes before kickoff … when raindrops began to fall. When the Saints were assessed a penalty, the Dons’ student section yelled, “You can’t do that!”

Priests shouted encouragement from the sidelines, and sometimes choice words to the officials. Saints came in 9-0, Cathedral Catholic 8-1, its only loss to the No. 1-rated team in the section, Helix.

Saints players walked to midfield before kickoff, pointed their fingers toward the Dons and talked smack. Defending their turf, the Dons pointed and woofed.

With less than five minutes to play and a light rain falling, it was tied 3-3. Cathedral scored twice in the final minutes to win 17-3, its latest victory in a rivalry unlike any other.

Family on his mind: Saints kicker/punter Seamus McMorrow wore a white wristband with the date 11-11-11 and the initials PSM and MEM written in black. Seamus’ grandfather, Paddy Stephen McMorrow, was diagnosed with lung cancer three months ago. Seaumus’ mother, Marian Elizabeth McMorrow, was diagnosed with breast cancer four weeks ago.

That winning feeling: Cathedral defensive lineman Casey Palid on the victory: “It feels absolutely incredible, especially it being our senior year. It might be the last time we play them. In this setting, to come out with a win … it’s amazing.”

Quotable II: Saints’ Derek Graham on the loss: “We’re not taking it as a loss, just a way we can get better. We know we’ll see them again.” The Dons and Saints are expected to be seeded one/two in the Division III playoffs.

Remembering a friend: Cathedral players wore eye-black with the number 23. Many wore wristbands with the number. They were honoring former Dons wingback Derek Thomas.

Thomas, who graduated last spring, has undergone more than 40 surgeries after a car accident in Bishop last August. Four people died as a result of the crash.

Turn off the heat: Cathedral Catholic’s mascot is nicknamed The Don, who wears what might best be described as an oversized soft helmet. Last night, The Don, a junior at the school, was making his debut. Asked why his predecessor stepped down, the mascot said, “Frankly, it’s pretty hot in here.”

Only at a private school: A conversation between two female Cathedral Catholic students outside the entrance. “Did you get a new car? What’d you get?” “A 2012 black Jetta.” “You’re so lucky.”
